Clinical Trial Summary

HDAC inhibitor chidamide and PI3K inhibitor linperlisib has shown clinical activity as mono therapy in PTCL. The combination of duvelisib and romidepsin is highly active against relapsed and refractory T-cell lymphomas including cutaneous T-cell lymphomas (CTCLs). The aim of this study is to further explore the efficacy and safety of HDAC inhibitor chidamide combined with PI3K inhibitor linperlisib in the treatment of relapsed and refractory CTCLs.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Recommended phase 2 dose (RP2D)(Phase 1)	Recommended phase 2 dose (RP2D) and/or maximum tolerated dose (MTD) will be established according to the incidence of dose-limiting toxicities (DLTs) of escalated doses of linperlisib.	4 weeks since the date of first dose
Primary	Objective response rate (ORR)(Phase 2)		evaluated every 3 months (up to 24 months)
Secondary	Progression-free survival	Progression-free survival was defined as the time from the date of enrollment until the date of the first documented day of disease progression or relapse, or death from any cause, whichever occurred first.	Baseline up to data cut-off (up to 5 years)
Secondary	Overall survival	Overall survival was defined as the time from the date of enrollment to the date of death from any cause.	Baseline up to data cut-off (up to 5 years)
Secondary	complete remission (CR) rate	Treatment responses were assessed according to the 2014 Lugano classification criteria	evaluated every 3 months (up to 24 months)
Secondary	adverse events	Graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0	evaluated every treatment cycle (up to 24 months)
